본 발명은 유압식 전동가위장치에 관한 것으로써, 상세하게는 대상물을 높은 절단력 및 정확한 절단력으로 작업수행할 수 있도록 하고, 절단과정에서 발생되는 안전사고를 예방하며, 크기를 소형화하고 전체적인 중량을 가볍게 구현함과 동시에 파손된 날의 일부만을 보다 손쉽게 교체할 수 있도록 한 것이다.The present invention relates to a hydraulic electric shear device, in detail, to enable the object to perform the work with a high cutting force and accurate cutting force, to prevent safety accidents occurring during the cutting process, to reduce the size and lightly implement the overall weight At the same time, only a part of the broken blade can be replaced more easily.

가위는 절단공구로 사용되며, 끝단에 날이 형성된 부재를 "X"형태로 힌지결합하여 지렛대의 원리로 대상물을 절단하는 것임은 주지된 것과 같다.Scissors are used as a cutting tool, and it is as well known that the object is formed by hinge-bonding a member having a blade formed at the end in the form of "X" to cut the object on the principle of the lever.

이와 같은 가위 중 가로수의 가지치기 또는 과일 등을 따내기 위한 가위는 나무의 높이에 대응하는 연장기구를 가위와 연결하고, 가위를 전동식 장치로 구현하여 스위치를 조작함에 의해 구동되도록 구성하고 있다.Scissors for pruning trees or pruning fruit among such scissors are connected to the extension mechanism corresponding to the height of the tree with the scissors, and implements the scissors by an electric device is configured to be driven by operating the switch.

상기된 종래의 전동식 가위장치는 모터의 회전력을 이용하여 가위날부를 구동시키는 장치가 출시되고 있으며, 모터의 회전력을 적정한 절단력 및 속도로 제어하기 위해 모터와 날부의 사이에 기어구성을 연결하여 구성된다.The above-described conventional electric shear device is a device for driving the scissors blade by using the rotational force of the motor has been released, it is configured by connecting the gear configuration between the motor and the blade to control the rotational force of the motor at an appropriate cutting force and speed. .

특히, 상기 모터를 이용한 전동식 가위장치는 외부에서 사용하기 편리하도록 하기 위해 배터리를 구동전원으로 채택하여 구성된다.In particular, the electric scissors device using the motor is configured by adopting a battery as a drive power source to make it convenient to use from the outside.

특히, 절단대상물이 종이나 연질의 부재가 아닌 가로수의 가지 또는 금속 와이어와 같이 경질의 것일 경우, 절단력이 약해 모터자체의 슬립이 발생되어 대상물의 절단이 불가능할 경우가 자주 발생되며, 절단된 면이 대단히 불량하게 된다.In particular, when the object to be cut is hard, such as a branch or metal wire, which is not a paper or soft member, the cutting force is weak so that the motor itself slips, and thus it is often impossible to cut the object. It becomes very bad.

또한, 상기 모터 및 기어로 이루어진 구성에 의해 가위자체의 크기가 대형화되고 높은 중량으로 구현되어 휴대 및 사용상의 불편함이 발생된다.In addition, the size of the scissor itself is increased by the configuration consisting of the motor and the gear is implemented in a high weight, causing inconvenience in portability and use.

더불어, 상기 모터 및 기어로 이루어진 전동가위는 상당히 고가의 제품으로 대상물을 절단하는 날이 파손될 경우 날을 형성하는 전체적인 구성을 교체해야 하기 때문에 상당한 시간적 손실이 발생되며, 날 전체를 교체함에 따른 경제적 손실도 발생된다.In addition, the electric scissors made of the motor and gear is a fairly expensive product, if the blade cutting the object is broken, because the overall configuration to form the blade is generated a considerable time loss, economic loss by replacing the whole blade Is also generated.

It consists of circuit structures, such as a microprocessor provided in the main body 1. As shown in FIG.

상기 교체날부(50)는 고정날(11)과 회전날(12)의 각 끝단부에 착탈가능하게 결합된다. 이와 같은 교체날부(50)는 절단 대상물을 절단하기 위한 절단날(11a, 12a)을 교체할 수 있도록 하기 위한 구성이다.The replacement blade portion 50 is detachably coupled to each end of the fixed blade 11 and the rotary blade 12. Such a replacement blade portion 50 is a configuration for replacing the cutting blades (11a, 12a) for cutting the cutting object.

이를 위해, 상기 교체날부(50)는 고정날(11)과 회전날(12)에 각각 결합편(11b, 12b)이 돌출 형성되고, 상기 결합편(11b, 12b)과 대응되어 결합되기 위해 형성된 결합홈(11c, 12c)이 고정날(11)과 회전날(12)에 각각 형성된다. 또한, 상기 교체날부(50)는 상기 고정날(11)과 회전날(12) 및 절단날(11a, 12a)을 관통하여 체결력을 제공하는 체결부재(60)가 결합되어 구성된다.To this end, the replacement blade portion 50 is formed on the fixed blade 11 and the rotary blade 12, the coupling pieces (11b, 12b) protruding, respectively to correspond to the coupling pieces (11b, 12b) is formed Coupling grooves 11c and 12c are formed in the fixed blade 11 and the rotary blade 12, respectively. In addition, the replacement blade portion 50 is configured by coupling the fastening member 60 to provide a fastening force through the fixed blade 11 and the rotary blade 12 and the cutting blades (11a, 12a).

여기서, 상기 체결부재(60)는 볼트를 적용하여 착탈 가능한 구성을 구현할 수 있게 되며, 상기 볼트는 접시머리 볼트로 적용하고 체결부재(60)의 머리가 접촉 되는 고정날(11)과 회전날(12)의 관통구멍 입구는 카운터 싱크 가공하여 체결부재(60)의 머리가 고정날(11)과 회전날(12)에서 돌출되지 않도록 구성된다.Here, the fastening member 60 is able to implement a detachable configuration by applying a bolt, the bolt is applied as a countersunk bolt and the fixed blade 11 and the rotating blade (the head of the fastening member 60 is in contact) The through-hole inlet 12 is countersink and is configured so that the head of the fastening member 60 does not protrude from the fixed blade 11 and the rotary blade 12.

상기된 것과 같은 전동가위장치의 구성에서 구동부(20)는 전원스위치(31)와, 안전스위치(32)를 포함하여 구성된다.In the configuration of the electric scissors device as described above, the drive unit 20 is configured to include a power switch 31, and a safety switch (32).

상기 전원스위치(31)는 유압기기(30)와 전기적으로 연결되어 유압기기(30)를 온/오프시키도록 구성된 스위치이며, 안전스위치(32)는 전원이 공급되는 라인과 연계되어 본체(1) 상에 1이상 설치된다.The power switch 31 is a switch that is electrically connected to the hydraulic device 30 is configured to turn on / off the hydraulic device 30, the safety switch 32 is connected to the line to which the power is supplied to the main body (1) It is installed at least one phase.

여기서, 상기 전원스위치(31)와 안전스위치(32)는 자력을 이용하여 스위칭 구동되는 솔레노이드 타입이거나, 이외에도 단순한 온/오프 스위치로 적용가능하다.Here, the power switch 31 and the safety switch 32 may be a solenoid type that is switched and driven using magnetic force, or may be applied as a simple on / off switch.

또한, 상기 구동부(20)는 제어부(40)에 의해 회전날(12)의 회전구동이 자동으로 인식되도록 하기 위해 피스톤(22)과 피스톤(22)과 대향되는 챔버(2) 내의 벽면 중 어느 일측 또는 양측에 센서(24)가 장착되어, 센서(24)간의 일정거리 또는 상호간의 센서(24)가 접촉되는 고정지점에 접촉시 역구동되도록 구성된다.In addition, the driving unit 20 is any one side of the piston 22 and the wall surface in the chamber 2 facing the piston 22 in order to automatically recognize the rotational drive of the rotary blade 12 by the control unit 40 Alternatively, the sensor 24 is mounted on both sides, and is configured to be driven back when contacting a fixed point where the sensors 24 are in contact with each other at a predetermined distance between the sensors 24.

도면 중 부호 4는 상기 본체(1)의 일측(도면상 하측)에 결합되어 작업이 불가능한 위치에 가위를 위치시키기 위해 일측에 결합되는 연장기구를 나타낸다.Reference numeral 4 in the drawings indicates an extension mechanism that is coupled to one side of the main body 1 and coupled to one side to position the scissors in a position where work is impossible.

상기와 같이 구성된 전동가위장치는 작업자가 절단대상물을 절단하기 위해 전원스위치(31)를 조작하여 전원을 온상태로 유지하고, 주변의 위험요소 존재여부 를 확인한 후 안전스위치(32)를 구동시켜 작업자가 절단부(10)에 의해 부상당하게 되는 우려를 해소하게 된다.In the electric scissors device configured as described above, the operator operates the power switch 31 to cut the cutting object, and keeps the power on, and checks the presence of dangers in the surroundings and drives the safety switch 32 to operate the operator. This eliminates the fear of being injured by the cutting portion 10.

즉, 상기 전동가위장치를 구동시키기 위해서는 반드시 1이상의 안전스위치(32)를 더 조작해야 하기 때문에 안전사고를 미연에 방지할 수 있게 된다.In other words, in order to drive the electric scissors device, at least one safety switch 32 must be further operated, thereby preventing a safety accident.

이 후, 작업자는 본체(1)에 연결된 연장기구(4)를 이용하여 절단부(10)를 절단작업위치로 이동시키면, 제어부(40)의 제어에 의해 절단부(10)에서 절단대상물을 절단하게 된다.Thereafter, when the operator moves the cutting unit 10 to the cutting operation position using the extension mechanism 4 connected to the main body 1, the cutting unit 10 cuts the cutting object under the control of the control unit 40. .

구체적으로, 상기 절단되는 과정은 제어부(40)의 제어신호가 입력되면, 유압기기(30)에서는 본체(1)의 유압라인(3)을 통해 유체를 공급하고, 공급된 유체는 피스톤(22)을 도면상 하측으로 밀어내어 구동로드(21)가 본체(1)의 내측으로 인입되고, 이로인해 구동로드(21)와 연결레버(25)에 의해 연결된 회전날(12)이 힌지결합된 지점을 중심으로 회전되어 절단대상물을 절단할 수 있게 된는 것이다.Specifically, in the cutting process, when a control signal of the controller 40 is input, the hydraulic device 30 supplies a fluid through the hydraulic line 3 of the main body 1, and the supplied fluid is a piston 22. To the lower side in the drawing, the driving rod 21 is introduced into the inside of the main body 1, whereby the driving rod 21 and the rotary blade 12 connected by the connecting lever 25 is hinged. It is rotated about the center to be able to cut the cutting object.

이와 같이 절단작업이 수행되면, 상기된 센서(24)는 상호 일정거리를 유지하거나, 상호 접촉되어 절단작업이 수행된 신호가 제어부(40)로 입력되고, 유압기기(30)는 챔버(2) 내의 유체를 회수하게 되며, 이 때 상기 피스톤(22)은 스프링(23)의 탄성력에 의해 원위치로 복귀된다.When the cutting operation is performed as described above, the sensor 24 maintains a constant distance from each other, or a signal in which the cutting operation is performed by being in contact with each other is input to the controller 40, and the hydraulic device 30 is connected to the chamber 2. In this case, the piston 22 is returned to its original position by the elastic force of the spring 23.
